Hi,
I’ve noticed for a few months now that the drawer full indicator on my litter robot 3 goes off after every cycle and needs to be reset. I’ve looked at help forums and came across a thread that asked to check the dfi sensor’s IR lights. A functional dfi sensor should emit 4 lights, but mine is only emitting 3 lights. Could this be the cause of my problems?
What can be done to correct this?
I purchased my litter robot on June 30th, 2021

Hello @Yj,
Welcome to RobotShop community.
We are sorry to hear that you are having trouble with your Litter-Robot.
Please try to clean the 2 green circuit boards of the DFI sensor using isopropyl alcohol and a Q-Tip to remove any rust or dust from them.
Then wash the plastic brackets if they are dirty and let them dry before putting the circuit boards back inside them.
Here’s a video to help you take these parts out of the base:
Let us know how it goes.
Sincerely,
Hi Ebram,
Thank you for your quick response.
I’ve tried what you suggested and it’s still not working properly - after one round of cycle, the reset blue light is blinking, indicating that the drawer is full (although there is nothing in the drawer).
Happy to try any other suggestions you may have.

Hello @Yj,
Thank you for your reply.
In this case, the DFI sensor will need to be replaced.
We can send you a new one to replace at home.
We will also need to see the 3 pairs of contact pins shown in the following videos:
Anti-Pinch Pins:
Bonnet’s Pin:
Base’s Pin:
No need to take them out of the robot, we only need to see them from the outside.
Finally, we would need the following:
Awaiting your reply.
Sincerely,

Hello @Yj,
Thank you for your reply.
The pins look okay so only the DFI sensor would need to be replaced.
We will forward you now to our replacement department to carry on with the process.
You will be contacted shortly via email with further details about the shipping.
Have a lovely evening, stay safe.
